Android Realtime Notification Socket Io
Realtime-notificationsIf you are making a web application which needs to update client in realtime, you can use this example to quickly write such an application in nodejs using socket.io. Redis pubsub is used as a data source in this example. You can use any other data source.Since these kind of applications are event-driven on server side (for example, a new message arrived for user) it is a good idea to use nodejs.Socket.io is used to maintain connection with the user. It uses websockets if available else uses fallback machanisms like long-polling.

UsageStart the server by cd serversudo nodejs server.jsNow hit on your browser Server side flowWhen the server starts, an http handler is created whose only task currently is to server index.html.There is socket.io handler which listens to all the websocket connections and manages them. It subscribes them to appropricate rooms and sends updates.Lastly there are two redis clients one of which subscribes to channels on redis and as soon as a message is received, it broadcasts them in appropricate rooms. The second client simply publishes dummy updates to redis channels to which the first redis client is subscribed to. Client side flowAs soon as the page load is done, socket.io client tries to connect to the server and on connection sends subscribe message for a particular channel. When updates are received it displays themI have documented the code as extensively as I could. Please email me in case of doubts.
News about the dynamic, interpreted, interactive, object-oriented, extensible programming language PythonIf you are about to ask a 'how do I do this in python' question, please try, or the #python IRC channel on FreeNode.Please don't use URL shorteners. I'm the author of the blog post and the answer to why we chose node.js is because of the following reasons:. There was already somebody using it in such manner (there's a cite to the article on the post). There's evidence that node.js performs well under load. There's a lot of hype around node.js. Although people consider hype to be a bad thing, it is in fact quite good, because it means that the community is large and the chances of the project being abandoned is minimal.

Socket.io provides a good WebSocket abstraction and can fallback to other means of real-time communications. (We had to support IE8).We didn't have much time to spend trying other event-based frameworks, so we had to go with the safest bet.That being said, I'm tempted to write the a similar blog post using Tornado.
